Variance-Ratio Tests Of Random Walk: An Overview
AbstractThis paper reviews the recent developments in the field of the variance-ratio (VR) tests of the random walk and martingale hypothesis. In particular, we present the conventional individual and multiple VR tests as well as their improved modifications based on power-transformed statistics, rank and sign tests, subsampling and bootstrap methods, among others. We also re-examine the weak-form efficiency for five emerging equity markets in Latin America. Copyright � 2009 The Authors. Journal compilation � 2009 Blackwell Publishing Ltd.
